Advanced mass spectrometry profiling of phenolic and minerals compounds in herbal beverages
(Food Chemistry, 2023-07-01)The global pandemic of COVID-19 has led to an increased interest in herbal infusions as natural remedies since 2020. This has also heightened the need for controlling the composition of these dietary ... -
Analytical parameters of an amperometric glucose biosensor for fast analysis in food samples
(Sensors, 2017-11-14)Amperometric biosensors based on the use of glucose oxidase (GOx) are able to combine the robustness of electrochemical techniques with the specificity of biological recognition processes. However, very ... -
Chloroplast engineering of the green microalgae Chlamydomonas reinhardtii for the production of HAA, the lipid moiety of rhamnolipid biosurfactants
(New Biotechnology, 2023-04-11)Hydroxyalkanoyloxyalkanoates (HAA) are lipidic surfactants with a number of potential applications, but more remarkably, they are the biosynthetic precursors of rhamnolipids (RL), which are preferred ... -
Creation of Ionically Crosslinked Tri-Layered Chitosan Membranes to Simulate Different Human Skin Properties
(Materials, 2021-06-23)In 2023, new legislation will ban the use of animals in the cosmetic industry worldwide. This fact, together with ethical considerations concerning the use of animals or humans in scientific research, ... -
Cyclic Homo- and Heterohalogen Di-λ3-diarylhalonium Structures
(Journal of the American Chemical Society, 2023-06-13)In the context of the ever-growing interest in thecyclic diaryliodonium salts, this work presents synthetic designprinciples for a new family of structures with two hypervalenthalogens in the ring. The ... -
Development of green/red-absorbing chromophores based on a coumarin scaffold that are useful as caging groups
(Journal of Organic Chemistry. Vol.82, n.10 (2017), p.5398-5408, 2017-05)We report the design, synthesis, and spectroscopic characterization of a series of push–pull chromophores based on a novel coumarin scaffold in which the carbonyl of the lactone function of the original ... -
High photostability in nonconventional coumarins with far-red/NIR emission through azetidinyl substitution
(Journal of Organic Chemistry. Vol.83, n.19 (2018), p.11519-11531, 2018-08)Replacement of electron-donating N,N-dialkyl groups with three- or four-membered cyclic amines (e.g., aziridine and azetidine, respectively) has been described as a promising approach to improve some ... -
Nitrogen positional scanning in tetramines active against HIV-1 as potential CXCR4 inhibitors
(Organic & Biomolecular Chemistry. Vol.14, n.4 (2016), p.1455-1472, 2015-12)The paradigm, derived from bicyclams and other cyclams, by which it is necessary to use the p-phenylene moiety as the central core in order to achieve high HIV-1 antiviral activities has been reexamined ... -
Novel grafted electrochemical interface for covalent glucose oxidase immobilization using reactive pentafluorophenyl methacrylate
(Colloids and Surfaces B: Biointerfaces, 2018-12-01)One of the most important factors for the proper functioning of enzymatic electrochemical biosensors is the enzyme immobilization strategy. In this work, glucose oxidase was covalently immobilized using ... -
Una visión moderna sobre la desactivación de cetonas aromáticas por beta-fenilos
(Afinidad. Vol.73, n.574 (2016), p.90-95, 2016-04)La desactivación por beta fenilos (en inglés, Beta Phenyl Quenching o BPQ) es una reacción que se produce a partir del estado triplete de cetonas aromáticas con un grupo fenilo en posición beta. Esta ...
